    Args:
        boxes (`torch.FloatTensor` of shape `(number_of_boxes, 4)`):
            Boxes for which the area will be computed. They are expected to be in (x1, y1, x2, y2) format with `0 <= x1

        Total loss as a linear combination of a negative log-likehood (cross-entropy) for class prediction and a
        bounding box loss. The latter is defined as a linear combination of the L1 loss and the generalized
        scale-invariant IoU loss.

        A dictionary containing the individual losses. Useful for logging.

        Normalized boxes coordinates for all queries, represented as (center_x, center_y, width, height). These
        values are normalized in [0, 1], relative to the size of each individual image in the batch (disregarding
        possible padding). You can use [`~Owlv2ImageProcessor.post_process_object_detection`] to retrieve the
        unnormalized bounding boxes.

        input_ids (`torch.LongTensor` of shape `(batch_size * num_max_text_queries, sequence_length)`, *optional*):
            Indices of input sequence tokens in the vocabulary. Indices can be obtained using [`AutoTokenizer`]. See
            [`PreTrainedTokenizer.encode`] and [`PreTrainedTokenizer.__call__`] for details. [What are input
            IDs?](../glossary#input-ids).
        output_hidden_states (`bool`, *optional*):
            Whether or not to return the last hidden state. See `text_model_last_hidden_state` and
            `vision_model_last_hidden_state` under returned tensors for more detail.

        Examples:
        ```python
        >>> import requests
        >>> from PIL import Image
        >>> import torch

        >>> from transformers import Owlv2Processor, Owlv2ForObjectDetection

        >>> processor = Owlv2Processor.from_pretrained("google/owlv2-base-patch16-ensemble")
        >>> model = Owlv2ForObjectDetection.from_pretrained("google/owlv2-base-patch16-ensemble")

        >>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
        >>> image = Image.open(requests.get(url, stream=True).raw)
        >>> text_labels = [["a photo of a cat", "a photo of a dog"]]
        >>> inputs = processor(text=text_labels, images=image, return_tensors="pt")
        >>> outputs = model(**inputs)

        >>> # Target image sizes (height, width) to rescale box predictions [batch_size, 2]
        >>> target_sizes = torch.tensor([(image.height, image.width)])
        >>> # Convert outputs (bounding boxes and class logits) to Pascal VOC format (xmin, ymin, xmax, ymax)
        >>> results = processor.post_process_grounded_object_detection(
        ...     outputs=outputs, target_sizes=target_sizes, threshold=0.1, text_labels=text_labels
        ... )
        >>> # Retrieve predictions for the first image for the corresponding text queries
        >>> result = results[0]
        >>> boxes, scores, text_labels = result["boxes"], result["scores"], result["text_labels"]
        >>> for box, score, text_label in zip(boxes, scores, text_labels):
        ...     box = [round(i, 2) for i in box.tolist()]
        ...     print(f"Detected {text_label} with confidence {round(score.item(), 3)} at location {box}")
        Detected a photo of a cat with confidence 0.614 at location [341.67, 23.39, 642.32, 371.35]
        Detected a photo of a cat with confidence 0.665 at location [6.75, 51.96, 326.62, 473.13]
